[squid-users] cache-peer and tls

[Eugene M. Zheganin]

Hello,


I'm using squid 4.6 and I need to TLS-encrypt the session to the parent 
proxy. I have in config:


cache_peer proxy.foo.bar parent 3129 3130 tls 
tls-cafile=/usr/local/etc/squid/certs/le.pem 
sslcert=/usr/local/etc/letsencrypt/live/vpn.enazadev.ru/cert.pem 
sslkey=/usr/local/etc/letsencrypt/live/vpn.enazadev.ru/privkey.pem 
sslflags=DONT_VERIFY_DOMAIN,DONT_VERIFY_PEER


But no matter what I'm doing, squid keeps telling in logs that he 
doesn't like the peer certificate:


2019/08/03 18:42:24 kid1| ERROR: negotiating TLS on FD 23: 
error:14090086:SSL routines:ssl3_get_server_certificate:certificate 
verify failed (1/-1/0)
2019/08/03 18:42:24 kid1| temporary disabling (Service Unavailable) 
digest from proxy.foo.bar

and then he's going directly bypassing the peer. :/


Is there any way to tell him that I don't care ?

I've also tried to actually tell him about the CA cert with 
tls-cafile=/usr/local/etc/squid/certs/le.pem above, this doesn't work 
either.


Thanks.

Eugene.
